Microphysics and Kinematics of a High Flash Rate Storm With a Bottom‐Heavy Charge Structure

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract An atypical thunderstorm with unusual lightning and charge structure characteristics propagated through Cordoba province, Argentina, during the austral warm season in late 2018. This storm exhibited echo tops near 10.5 km, with high lightning activity concentrated at low altitudes.

Vertical Structure and Energetic Constraints for a Backscatter Parameterization of Ocean Mesoscale Eddies

Journal of Advances in Modeling Earth Systems
Mesoscale eddies modulate the stratification, mixing, tracer transport, and dissipation pathways of oceanic flows over a wide range of spatiotemporal scales.

Reduced trapping efficiency of mesoscale eddies under eddy-eddy interactions

npj Climate and Atmospheric Science
Abstract Oceanic mesoscale eddies are commonly assumed to act as coherent structures that trap and transport water masses over long distances. However, recent Lagrangian studies suggest that long-lived coherent structures in the ocean are much more limited than implied by Eulerian eddy boundaries.

Contrast in the Boundary Layer Convergence Lines at Desert−Oasis Border With Different Vegetation Gradient

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Motivated by an observed asymmetry in boundary layer convergence lines (BLCLs) between the Kubuqi and Ulan Buh desert borders of the Hetao Oasis in northern China, this work aims to document the differences in BLCL frequency and convective initiation and their potential drivers.

Mesoscale Eddy‐Induced Sharpening of Oceanic Tracer Fronts

Oceanic fronts are ubiquitous and important features that form and evolve due to multiscale oceanic and atmospheric processes. Large‐scale temperature and tracer fronts, such as those found along the eastward extensions of the Gulf Stream and Kuroshio ...

A Generation Mechanism of Thorpe‐Detected Turbulence: A Case Study Using WRF Model Simulation

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Turbulence in the free atmosphere has been widely estimated using the Thorpe method, which identifies vertical inversions in potential temperature profiles as evidence of overturning. However, the mechanisms driving Thorpe‐detected turbulence remain poorly understood, due largely to limitations in spatial and temporal resolution of ...

The spatial distribution relationship between mesoscale eddies and chub mackerel and its preliminary analysis of causes in the Northwest Pacific Ocean

Frontiers in Marine Science
Chub mackerel (Scomber japonicus) is a commercially important small pelagic fish species whose distribution is strongly influenced by marine environmental conditions.

Effects of Mesoscale Eddies on Southern Ocean Biogeochemistry

AGU Advances
Abstract The Southern Ocean is rich in highly dynamic mesoscale eddies and substantially modulates global biogeochemical cycles. However, the overall surface and subsurface effects of eddies on the Southern Ocean biogeochemistry have not been quantified observationally at a large scale.

Resolution Dependence in a Global Atmospheric Simulation From km to 220 m Grid Spacing

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We conducted a 220‐m mesh simulation over the global domain with realistic topography. This can be called a first “global large‐eddy simulation” (GLES) for deep convection. The resolution dependence across km‐ to sub‐km scales and sensitivity to turbulence schemes are investigated.

Effects of Mesoscale Eddies on Acoustic Propagation with Preliminary Analysis of Topographic Influences

Journal of Marine Science and Engineering
This study investigates underwater acoustic propagation patterns under mesoscale eddy conditions through numerical modeling and parametric analysis. A mathematical model of mesoscale eddies was developed, and acoustic transmission loss was computed using
